MACHINE FOR CUTTING MATCH-SPLlNTS.

SPECIFICATION forming part of Letters Patent No. 250,676, dated December 13, 1881. Application filed May 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, ISAAC PIERGE,of Alma, Gratiot county, Michigan, have invented an Improvement in Machines for Cutting Match- 1iplints, of which the following is a specifica- The nature of this invention relates to certain new and useful improvements in the construction of machines designed for cutting match-splints from a round log; and the invention consists in the peculiar construction, arrangement, and various combinations of the parts, all as more fully hereinafter described.

Figure 1 is a central vertical section. Fig. 2 is a front elevation.

In the accompanying drawings, which form a part of this specification, A represents a suitable frame which carries the working parts of my machine, and in the rearward-projecting guides B of which is arranged the gate O,which carries the knife D. This gate 0 is connected by means of rods to to the center arm,b,of the rock-shaftE, which is properly j ournaled across the lower'part of the frame A.

The arms d of the rock-shaft E are connected by means of the rods 0 to the gate F, which has a vertical sliding movement in the guides h in the frame A. In the lower portion of this gate F is properlyjournaled the shaft G. Upon the shaft G is secured a cutting-wheel, H, the periphery of which is formed of cutters 'i,which are designed to cut the face of the log in advance of the knife D, as hereinafter set forth.

I isashaft, which finds bearings in the frame, as at 7;, and is designed to receive the section or log J, which is of the length of the desired splint or splints. This log or bolt is clamped against the shoulder 0 of the shaft by means of the thumb-nut as is clearly shown in Fig. 2, in practice the parts being arranged substantially as described.

The shaft G and the cutting-wheel H are rotated from any convenient source of power by means of a belt upon the pulley L on the end of the shaft, the face of the cutting-wheel H coming in contact with the face of the log J in the rotation of the shaft. A like movement is imparted to such log and its shaft, while it is designed that the weight of the gate F, with its shaft and cutting-pulley, shall be sufficient to embed the cutting-knives i in the timber or face of the log J. The continued rotation of this log J causes the knife D to cut a veneer from the log at the base of the cut formed by the knives 2', the action of the two cutting devices upon the log being such as to out square match-splints from the face of the log in its rotation. As the log decreases in size the cutter H, with its frame F, slides downward in the guides h, so that the rotated cutter H will con tinually rest upon the log, and in this movement of the frame F the rock-shaft E by means of the rods 0, is caused to partially rotate, thereby drawing the frame 0 forward by means of the rods a, so as to keep the cutter-knife D in engagement with the log. After the log has been cut up the gate F, with its attachments, may. be raised by means of a suitable cable, 0, passing over suitable pulleys, t, which will at the same time retract the knife D and its frame, in which position they may be retained by securing the end of the cable 0 to any proper stop or pin.

If desired, the shafts G and I may be formed so as to project beyond the sides of the frame in which they are journalcd and receive upon their respective ends the on tting-wheel H and the round bolt or log J, and at the same time the power may be applied directly to the shaft I, compelling the bolt to turn the cutting-knife H, although I now prefer the arrangement of parts as shown and described.

What I claim as my invention is- 1. In a machine for cutting match-splints from a round block, the rotating knives H and the sliding knife D, in combination with the rock-shaft E, arms I) d on said rock-shaft, frames (3 and F, carrying the knives, and suitable connections between the frames and the rock-shaft arms, substantially as described.

2. In a machine for cutting match-splints, the rotary cutter H, constructed to slide in vertical guides, and adapted to fall and cut into the face of a match-block by its own weight, in combination with the sliding cutter D and the rock-shaft E, arms I) d, and connectingrods 6 a, for causing the cutter D to move simnitaneousiy with the cutten H toward the a, for compelling the simultaneous advancecenter'of the match-block, substantially as dement or retraction of the cutters H and E, subscribed. stantially in the manner described.

3. In a machine for cutting match-splints, ISAAC PIERCE. 5 and in combination with the frame A thereof Witnesses:

and the sliding frames F and C,the rock-shaft H. S. SPRAGUE,

E, connected to said frame by the rods 6 and E. SOULLY.
